,3 Claims. My present invention relates to elevating mechanism, and more particularly to automatic automobile window elevating mechanism.

In the automobile trade there has been a ion felt want for a window sash which can be easily raised without thev laborous use of cranks and I similar devices generally in use.

,In my present invention, I have designed an elevating mechanism which is simple of construction and automatic in operation. My improved mechanism permits the operator to elevate the window sash easily, quickly or slowly as the desire may be' by simply pressing a lever on the door frame. The sash may be instantly stopped at any desired opening, or the entire sash may be raised and locked with one motion of the operator's hand and within a second or two of time.

The principal object of my invention is therefore, an automatic window sash elevatingmechanism;

Another object is an automaticautomobile window sash elevating mechanism operated by means of pressure applied against a release mechanism; v

Another object is an elevating mechanism of a window sash which may be operated fast or slow and stopped at any desired point by the simple increase or decrease of pressure applied to a re lease mechanism located on the window frame remote from the lower limbs of the operator;

Another object is anautomatic window sash elevating mechanism which allows the sash to be pulled down easily and which will maintain such sash in any position from which it may be instantly released a short distance or all the way.

Other objects and novel features comprising the construction and operation of my device will be apparent as the description of the same progresses.

In the drawing illustrating the preferred embodiment of my invention:

Fig. 1 is a back elevation of an automobile door to which my invention has been applied, the covering material on the lower half of the door 45 having been removed to show the mechanism more clearly; v

Fig. 2 is a cross-section taken on the line 2-2 of Fig. 1 showing a side elevation of the locking mechanism;

0 Fig. 3 is a plan cross-section taken on the line 3-3 of Fig. 1 showing the release lever and part of the iocking'mechanism, and

Fig. 4 is another plan cross-section taken on the line 4-4 of Fig. 1 showing further details of '55 the lockingmechanism.

Referring more in detail to the drawing and particularly to Fig. 1, It indicates the. conventional door frame'of an automobile door, the

lower half of which is closed the sash elevating mechanism being inclosed between the outside sheet metaifinish and the inside covering, not

shown, H indicates a transverse frame member upon the back side of which I have attached my elevating locking members. Directly behind the frame I I I have attached a vertical plate l2. On the left side of the plate I 2, as viewed in Fig. 1, I have provided slotted openings l3, the top slot of which is shown in dotted: lines being hidden by the frame H. The slots I3 are counterbored on the sideof the plate l2 ad- Jacent the frame II, as shown in Fig. 1 for the purpose of receiving the flat head of a bolt It also indicatedin Figs. 2 and 4. On the right-hand side of the plate l2, as viewed in Fig. 1, I have attached by means of screws I5 a vertical slide guide It which is immovable. On the Opposite side of the plate i2 opposed to the guide It is a corresponding tapered guide member l'l in which the bolts II are firmly set, the two guides l6 and -I1 together forming a slide-way. The guide member Il comprising a part of the said slide-way is provided with an inner slide-way surfacewhich is inclined toward the guide member iii, the space separating the members It and I! being narrower at the top than at the bottom, in which is located a slide Ill. The slide I8 is indirectly connected with the glass window sash I9 through a bracket 20 which is attached to a window sash frame 21, the pivoted end being connected with the slide I8 by means of a pin 22 fixed in the said slide. On either side of the slide-way I have provided elevating compression springs 23 which are seat'ed against the under side of the window sash slide i8 operates is slidably mounted on the plate plate l2 and the movable guide I! such that the guide I! is normally thrust upward and inward against the slide I8 thereby tending to pinch or jam the slide l8 against the fixed guide member 5 l6 and halt the upward movement of the window sash at any point within its normal travel. It is this slide-way mechanism to which I previously referred as "my elevating locking members". l0 Pivoted to the back side of the door frame H by means of the pin 21 is a release lever 28. One end of this release lever 28 engages in a slot 29 located in the upper portion of the movable guide member ll. The other end of the release 16 lever 28 is connected with a handle 30 through the medium of a socket 3|, the handle being pivoted at 32 to the door frame H.

Assuming that the window sash and sash frame isin a lowered position at which time the 0 slide l8 will be down toward the bottom of the slide-way and the movable guide member I! will be snugly pressed against the slide 18 which in 'turn is snugly pressed against the immovable guide member l6, and owing to the fact that the 25 spring as is holding the adjustable guide member ll against the slide 3 no upward movement of the sash l9 will occur but, if the hand guide I! acts in the nature of a brake shoe on the slide l8 and the movement is so slight that the sash can be raised very slowly or very rapidly as the desire of the operator may be.

Having thus described my invention what I 40 claim as new is:

1. A friction loci: for self raising window sashes comprising a tapered slideway located in the frame of said window one side of said slideway being movable in an upward and inward direction and normally being held against a slide block engaged in said slideway by means of a spring member attached to the movable and permanent portions of said slideway, a hand operating lever and link member pivoted in the said window frame adapted to depress said slidable portion of said slideway for the purpose of releasing said slide block, a pivoted link member connecting said block with the bottom of said sash.

2. A friction lock for automobile door window sashes or the like comprising, a tapered'slide attached to the bottom of said sash, a tapered slideway adapted to receive said slide, one side of said tapered slideway being slidably mounted on the permanent part of said slideway and being further adapted to maintain an inward and upward thrust against one side of said slide by means of a spring tension member connecting said slidable portion with said permanent portion of said slideway, a hand operating lever and link pivoted to the frame of said window and adapted to release said slidable slideway member for the purpose of permitting said slide to move in said slideway.

3. A friction lock for self raising window sashes comprising a tapered slide attached to said sash and engaged in a tapered slideway, one side of said slideway being movable in an inward and upward direction and normally engaging said slide in a friction manner, spring means attached to said slideway adapted to maintain said movableportion of said slideway in friction contact with said slide, means for releasing said slide connecting-said movable slideway member.
